Vos données sont un bordel ? Bienvenue au club. Entre les CSV qui mentent, les bases de données qui jouent à cache-cache et les data scientists qui promettent des miracles… On dirait un épisode de *Black Mirror*. Dans le cadre de mon travail : je nettoie, je structure, et je livre des données *prêtes à l’emploi* (sans magie noire). A recette : - Moins de *"Je vais révolutionner votre business avec l’IA"*… - Plus de *"Vos données sont propres, fiables, et accessibles. Enfin."* Exemple : j'ai sauvé un client dont les données ressemblaient à une soupe de lettres. Maintenant, elles dansent comme des ballerines. Besoin d’un exorciste de données ? Contactez-moi. #DataEngineering #Humour #DataCleaning #NoBullshit #Tech #Innovation #Fun

🐘 Αποκωδικοποιώντας τα #NULL!, #VALUE! και #REF! στο @ONLYOFFICE

Στο νέο post:

🔹 Γιατί η =SUM(A1:A5 C1:C5) επιστρέφει #NULL!
🔹 Το #VALUE! από αόρατα spaces ή αριθμούς ως κείμενο (και πώς τα φτιάχνει η VALUE() & TRIM() )
🔹 Το #REF! – ο "δολοφόνος" όταν διαγράφετε γραμμές

👉 Όλα αυτά, με παραδείγματα, στο άρθρο του ONLYOFFICE (Open Source, δωρεάν, συμβατό με .xlsx)

Data engineering = 80% nettoyage, 20% glamour. Exemple : 3 semaines pour corriger doublons. Solution : automatisation, documentation. #DataEngineering #Tech #Humeur #DataCleaning #Réalité ... https://www.linkedin.com/posts/gabriel-chandesris_dataengineering-tech-humeur-share-7455896944264081408-Ln7L

🧹 "La vérité crue sur le data engineering : 80% de nettoyage, 20% de glamour" Quand j’ai commencé en data engineering, je rêvais de **machine learning** et d’**IA révolutionnaire**. La réalité ? **Nettoyer des données sales** 90% du temps. 🔹 **Exemple concret** : - **Projet "sexy"** : "On va prédire le BullShit avec du ML !" - **Réalité** : - 3 semaines à **corriger les doublons** dans les données clients. - 2 semaines à **standardiser les formats** (dates, adresses). - 1 semaine à **documenter** pourquoi on a fait ces choix. 🔹 **Pourquoi c’est important** : - **Des données propres = des indicateurs fiables**. - *Exemple* : Un client a évité une **erreur de 500k€** grâce à un nettoyage rigoureux. - **Un pipeline bien conçu = moins de stress en prod**. 🔹 **Comment rendre ça moins pénible ?** 1. **Automatisez** : Scripts Python pour les tâches répétitives. 2. **Documentez** : Un README clair évite de tout recommencer. 3. **Célébrez les petites victoires** : "Aujourd’hui, j’ai supprimé 10 000 doublons !" → **C’est déjà ça.** 💬 **Quel est votre pire cauchemar de nettoyage de données ?** #DataEngineering #Tech #Humeur #DataCleaning #Réalité

Evil AI would force its human slaves to do data cleaning and feed it with structured data.
